Features

Like most other NAS manufacturers, Thecus has a common operating system for its NASes. The current operating system is ThecusOS 7. You can download the complete 160 page OS7 User's manual here. The screenshot below shows the N4350 desktop.

The control panel allows you to configure the N4350.

The Thecus website has a link to a live demo for ThecusOS 7. The linked page includes credentials for the Admin account and a user account. Both are read-only. I clicked on the Live Demo link and it took me back to the parent ThecusOS7 page, so apparently, the live demo feature isn't currently working.

Like most other NASes, Thecus provides a library of applications that can run on your NAS. However, Thecus' app library is very small, offering only the 13 apps shown below. Of course, not all applications will run on entry-level NASes. Notable apps include the Plex and Twonky media servers and surveillance system for use with IP cameras.

Performance

Firmware version 3.02.02.11.a388 (Thecus OS7) was loaded onto the N4350 and performance tests were run using the Revision 5 NAS test process. All tests were run using Western Digital Red 1 TB WD10EFRX (x4 SNB supplied). Note: While the N4350 supports both the EXT4 and the XFS filesystems, all tests were run using EXT 4.

With the exception of the RAID 0 File Copy Read test, all of the File Copy Read and Write tests for the N4350, as well as the QNAP TS-431P, were in excess of 100 MB/s. We noted the same lower performance for RAID 0 File Copy Read when we reviewed the N2350 last year. In general, the TS-431P outperformed the N4350 on virtually every test with the exception of Network backup and NASPT Content Creation for all RAID levels. The N4350 had an exceptionally speedy network backup throughput of 101.4 MB/s compared the TS-431P's 36.6 MB/s, which is more typical for this benchmark.

The chart below shows the Total NAS scores for the seven least expensive two-bay RAID 1 NASes. The Thecus N4350 has a Total NAS ranking of #9 compared to the #4 ranked QNAP TS-431P.

The performance summaries below show the QNAP TS-431P outperformed the Thecus N4350 in every category except Mixed Read Write and Backup. In the Mixed Read Write category, the QNAP's scores were dragged down by its lower throughput on content creation as noted above. Similarly, relatively poor Network Backup dragged the QNAP's Backup category score down even though the USB3 NTFS backup throughput for the QNAP was almost twice as fast as the Thecus' throughput.

Closing Thoughts

We often present our NAS Ranker table sorted by price rather than by rank because it makes it easier to spot a good value. If a NAS is cheaper but has a higher ranking, it's probably a pretty good deal. In this case, the slightly cheaper #4-ranked QNAP TS-431P has a clear edge over the #9-ranked Thecus N4350.

If you're looking at mid-range priced 4-bay NASes, the QNAP TS-431P, with dual Ethernet ports and a third USB 3.0 port, is a clear choice. About the only reason to consider the N4350 is if you want both iSCSI target and initiator. As the N4350's #9 Total NAS ranking indicates, it performs very similarly to the #10-ranked ASUSTOR AS1004T, but the ASUSTOR NAS is $70 cheaper.

[Note: Our Amazon pricing is updated every night directly from Amazon data feeds, taking the lowest price Amazon reports. However, we're seeing more often this "lowest" price isn't really the best deal. It may ship from a little third-party seller located outside the U.S and not include shipping and import fees. The bottom line is that if you're interested in a product, click over to Amazon to check the latest pricing.]
